Seven parallel dialers to assess for European B2B teams

Your SDRs have lists ready for several European countries. Before choosing a parallel dialer, check which caller IDs they can use, what a prospect hears after pickup and whether the right call result gets back to your CRM.

A parallel dialer calls several numbers for one rep at the same time and connects the first person who answers. A phone system with many simultaneous outbound calls across an entire team is not necessarily a parallel dialer for each SDR. A power dialer generally moves through a list one number at a time. The highest line count is not automatically the best setting: every additional ringing line can become a cancelled call when someone else answers.

Disclosure and method. Ubic publishes this comparison and is one of the seven products listed. Comparison established on 6 October 2026, based on publicly available product, help and pricing pages from the vendors. We included products whose own documentation describes several simultaneous calls for one rep and whose offer may serve a European B2B team. The list is illustrative, not exhaustive or ranked: it spans focused tools, a broader cloud phone system and two global outbound suites. We have not independently tested call quality, detection accuracy, support language, data processing or country coverage. A feature advertised on a website still needs checking for your plan and countries.

Use the same decision criteria for all seven: simultaneous lines per rep; destinations and local caller IDs; whether the CRM receives the right call result; support language and hours; data hosting, subprocessors and DPA; then the total quote for seats, calling, numbers, add-ons and commitment. Public pages rarely settle all of these for a specific team.

Seven options to assess

Ubic: a focused B2B calling session

Ubic calls up to three numbers in parallel, filters voicemails and gives the answered call to an SDR. Its public plan includes numbers and number rotation. Its HubSpot guide describes a concrete workflow: a HubSpot contact list becomes a calling list in Ubic; the status chosen after a call can update a configured HubSpot property.

This is a sensible trial for a team doing regular B2B outbound, especially if it wants to keep a modest number of lines per rep. Confirm the countries and number types you need in a demo. We do not claim a verified Salesforce connector here; if Salesforce is central to your operation, require a live integration check first.

Skipcall: business telephony with parallel calling

Skipcall’s site documents both a sequential power dialer and a four-line parallel dialer. It also presents web and mobile telephony, CRM connections and published plans. That broader phone setup may suit a team replacing its business telephony at the same time as its prospecting tool. Confirm which plan enables parallel calling, the conversation allowance, the countries and number types, and the price for your actual usage.

Minari: calling sessions with list preparation

Minari’s site describes up to five contacts called at once and CRM activity sync. Its pricing page lists number enrichment as an optional add-on. That may be relevant when an SDR team wants to prepare a list and call from the same workspace; include the add-on in the quote if needed. Its public material does not establish a universal price, support language or every European caller ID for a specific contract; request those details and the data-processing terms before comparing quotes.

Paradial: a parallel calling option

Paradial’s site presents parallel calling, an offered trial and a public monthly headline price. Its pages show different examples of active lines, so ask for the current written plan, trial conditions, included seats, numbers and calling allowance. Verify each destination and caller ID in the same way as for every other vendor.

CloudTalk: broad phone system with a parallel add-on

CloudTalk lists a Parallel Dialer add-on that can call up to ten numbers at once, detect answering machines and queue another attempt. Its pricing page also describes international number and calling options across European markets. The phone system has inbound handling, routing and other functions beyond an outbound SDR session.

That broader scope may suit a team that needs one provider for inbound and outbound calls. The parallel function is an add-on to a base plan, so compare the complete package rather than the add-on figure alone. Ask CloudTalk for the exact country bundle, number types and CRM tier for your account.

Orum: a larger outbound programme

Orum’s dialer page describes power and parallel modes with up to five lines. Its international page says it can call into more than 160 countries and regions, with international numbers available on request. Its pricing page requires a minimum of nine seats and directs buyers to a quote.

For a larger SDR organisation already investing in coaching and high-volume calling, that may be worth examining. For a small European team, the seat minimum and the details of local numbers, data processing and supported destinations need checking early. A global calling headline is not a promise that your preferred caller ID is available in every country.

Nooks: adaptive line selection

Nooks documents standard parallel calling on two to five lines, alongside adaptive modes that adjust active lines based on predicted pickup. Its own help page says the adaptive modes require a Parallel Dialing seat, a standard Nooks number and workspace opt-in to data sharing.

This can be relevant if a team wants line pacing to adjust during a session. Ask for the actual countries and number types in your contract and review the data-sharing choice with your privacy team. We did not find enough public evidence to treat a specific European number setup as guaranteed.

Why Aircall and HubSpot are separate choices

Aircall’s Power Dialer help page says it calls imported numbers in order, with time between calls for notes and tags. HubSpot now has a native sales power dialer for Sales Hub Enterprise that queues contacts and moves through calls. Both can be good choices when one-at-a-time calling fits. Neither of those documented modes should be labelled a parallel dialer merely because the word “dialer” appears.

Run the same trial with each vendor

Put a small, permissioned B2B test list in each tool, including a number you control. Listen to what happens from pickup to the rep’s first word. Check which calls are cancelled when another line answers and how those contacts return to the list. Record one voicemail false positive and one callback, then check the disposition in your CRM.

Finally, obtain the quote for your actual countries, numbers, seats, minutes and commitment. For Europe, local-number availability and rules differ by country. A pricing page cannot settle those details for your own outbound programme.

If you want to see the focused three-line approach, book an Ubic demo with one of your lists and the countries your SDRs call.
